FUNNEL.

Application filed June 6, 1927. Serial No. 136,866.

This. invention v relates particularly to funnelsfor large service, such as the transferring of gasoline, kerosene and motor oil from tank wagons or other sources to such steel drums as are used at automobile scivice stations for receiving and dispensing suchliquids. v v f I In funnels for suclu transfer 'of these liquids in relatively large volume into steel drums and, similar receptacles, various conditions must be met ton-endorthe operation practical. M 6 I ,1 Among those conditions are strength oi thestructure, stability of the funnelwhen a plied to the drum, rapid downward flow tlgrough the funnel, avoidingwaste bysurg- 'ing, 'slo ping and spraying, and adaptability of t e funnel to, different sizes of drum connecting members.

The object of this invention is to meet these, conditions in a practical way. i In the accompanying drawings, f Fig. 1 is an upright section on the axial line ofthe funnel; f

Fig. 2 is :a plan of one half of the same funnel; v i r Rig. ,3 is a horizontal section on the line, of ig- J Fig, 4is a horizontal 4 4,jof Fig. 1; I 6 Fig. 5 is a horizontal section on the line, 5-5,ofFig. 1. Referring to said'drawings, A is theupper Wall of a steel drum or similar receptacle. is a connecting member forming a port leading into the drum and ordinarily closed with a cap (not shown). Thebody of this member is tubular and interiorly screw threaded and has a flange, B1,;overlappingand welded or brazed to the outer face of the wall, A. h p A thick and firrn'tubular metal neck, has an upper exteriorly screw-threaded part formed to inter-fit with the interiortlnreading of the connecting member. B. At the upper end of the neck, C, is an upward extension, C1 of smaller external diameter than the external diameter of the part which is screw-threaded Thus there is formed 'an annular shoulder, C2. 7 i

On that shoulderis seated the lower end of actruncated, conical, sheet metal section, D, of the body of the funnel, the lower ,section' on the line,

' opening in said section "being small enough to closely fitagainst the outer face of the :extension, C1,, while said section rests on the shoulder, C2. l/Velding metal, D1, joins the lower edge of the section, D, to the shoulder, C2. The upper edge of the section, D,

is flared horizontally outward to form a flange, D2. An, upright cylindrical sheet metal section, E, has at its lower edge an outward directed flange, El, resting all the way around on the flange, D2. The flanges D2 and E1, are joined by welding or otherwise to make a strong union. The upper edge of the section, E, has an outward-diiected flange, E2. A flange ring, F, has its outer edge over-lapping and welded' or otherwise secured to the flange, E2. Said flange ring extends horizontally inward 1a distance s'uflicient for the purposes hereinafter mentioned. The inner edge of said ring is preferablyhent downward, as shown by the drawings.

The neck, U,1s shown as having a lower exte riorly threaded part of smaller exterior diameter than said upper threaded part. The threading on said lower part is formed to fit the interior threading of a smaller con necting member, '13, the steel drums now in general use for receiving such liquids having connecting' 'members of two standard sizes." I p Below the second threading, the neck, C, has a downward extension, G4, in plain tubular form. This serves two purposes. The

lower end of the vent tube. J The'vent tube, G, has its upper end open and near the lower faceot the flange ring,

F, and it extendsdownward along the inner face ofthe wall of the section, E, and along the inner face of the wall of the section, D, and then downward through the neck, C, closefto the inner face/of the latter, and to ,the bufiier extension, Cat. There this tube is turned horizontally 'into a port, C5,

formed in the extension, C4, whereby the lower end of the vent tube is given communication with the interior oil the steel drum. The drawings show the vent tube welded or similarly secured to the sections, Eand D, at G1. The lowerend of said 'tubeisshown It is to be observed that the vent tube,

, G, is entirely within the apparatus; that the upper end oflsaid tube is shielded by the ring, F, and the tongue, H, in such manner as to avoid the pouring of liquid into the upper end of said tube when the liquid is being poured from the tank wagon into the 'funnel for downward flow through the neck, C.

At the same time the ring, F, and the tongue, H, prevent flow of liquid upward and out of the upper part of the funnel vent tube.

when liquid surges upward through the Then the ring, F, and the tongue, II, deflect the upward stream of liquid and compel said stream to spread and then descend into the body of the funnel. In this connection it is to be noted that the steel v tanks which are to be served by these funnels are large and hold a'great quantity of liquid and when the liquid flows rapidly downward through the funnel from the large tank wagon or similar holder, at times strong surging'of the liquid in the large drum or tank is developed. The primary function of this vent tube is to conduct air from the interior of the drum upward through'the funnel'into the atmosphere during the downward flow of liquid into thedrum. The vent tube' and the parts associated therewith are so constructed as to permit the upward and outward flow of air and also to permit upward flow of liquid, during surging, without slopping or splash ing out of the funnel. It will be seen that usually the liquid will not reach and enter the vent tube until enough liquid has been delivered into the drum to bring it well to-v ward the lower end of the neck, Then surging of the liquid will at times cause the liquid to enter and rush upward into and sometimes through the tube. Giving the lower end of the tube the lateral portkas above described, reduces the tendency of the liquid to enter the tube, the liquid tendingmerely to beat against the lower wall of the tube.

It is to be observed that the lowerendfof the vent tube is well secured and protected in the neck, C, the'mouth of the tube being lateral and confined within the wall of the buflerextension, C4; WVhen the funnel is V detached from the drum, it may be set with the extension, C4, resting on any surface without tendency to admit dirt or other whereby a shoulder is formed, and a tapering body having its lower end surrounding said extension and, seated on said shoulder and secured to said neck.

2. In a funnel, the combination of a ward extension of smaller external diameter tubular neck having an upper exteriorly threaded part formed to fit the interiorof a tank connecting member and having a lower exteriorly threaded part formed to lit the interior threading of a smaller tank connecting member, and saidneckh'aving ing member and said neck having'an up ward extension of smaller external diameter whereby a shoulderis formed and said neck having at its-lower end a buffer extension, and a tapering body having its lower end sur rounding saidextension and seated on said shoulder and secured to said neck.

4. In a funnel, the combination of a tubular neck having an upper exteriorly threaded part formed to fit the interior of a tank connecting member and having a lower exteriorly threaded pait formed to fit the interior threading of a smaller tank con- ,necting member, said neck having an upward QXtGIlSlOIiOf smaller external diameter than the exterior diameter of said threaded part whereby ashoulder is formed and said neck having at its lower end a buffer extension, and a tapering body having its lower end surrounding said extensionand'seated on said shoulder and secured to said neck.

5. In a funnel, the combination of an exteriorly threaded tubular neck formed to fit the interior threading of a tank connecting member and said neck having an upward extension of smaller external diameter 7 whereby a shoulder is formed and saidneck having at its lower end a buffer extension, a tapering body having its lower end surrounding said extension and seated on said shoulder and secured to said neck, and fa vent tube extending downward through the body and said neck and opening laterally through the buffer extension. z

6. In a funnel, the combination of a tubular neck having an. upper exteriorly threaded part formed to fit the interior of a tank connecting member and having a lower exteriorly threaded part formed to fit the interior threading of a smaller tank connecting member, said neck havin an upward extension of smaller external diameter than the exterior diameter of said threaded part whereby a shoulder is formed and said neck having at its lower end a buffer extension, a tapering body having its lower end surrounding said extension and seated on said shoulder and secured to said neck, and a vent tube ext-ending downward through the body and said neck and opening laterally through the buffer extension.

7 In a funnel, the combination of an exteriorly threaded neck, a body, a flange ring on the upper part of the body, a downwarddirected tongue at said ring, and a vent tube extending upward through said neck and the body and nearly to said ring and between said tongue and the wall of the body.

8. In a funnel, the combination of an exteriorly threaded neck, a body, a flange ring on the upper part of the body, and a vent tube opening laterally through said neck and extending upward through said neck and said body and nearly to and opening under said flange ring.

9.
